Skip packaging test log file stashing once tests have failed (#58520)
When a packaging test completes, we move the elasticsearch logfile to
another location so that if the next test fails, we have just the
contents of the test that ran. However, once the test fails, we continue
trying to move this file in the subsequent calls to teardown when the
rest of the tests are skipped. This commit skips the teardown step once
we have marked the suite as failed.

Remove vagrant debug logging (#58629)
Previously we had odd issues in CI with vagrant which we attempted to
diagnose by enabling debug logging within our vagrant commands. However,
the debug logging didn't explain anything additional to the failures,
and it is extremely verbose. This commit removes the debug logging.

Allows SparseFileTracker to progressively execute listeners during Gap processing (#58477) (#58584)
Today SparseFileTracker allows to wait for a range to become available
before executing a given listener. In the case of searchable snapshot,
we'd like to be able to wait for a large range to be filled (ie, downloaded
and written to disk) while being able to execute the listener as soon as
a smaller range is available.

This pull request is an extract from #58164 which introduces a
ProgressListenableActionFuture that is used internally by
 SparseFileTracker. The progressive listenable future allows to register
listeners attached to SparseFileTracker.Gap so that they are executed
once the Gap is completed (with success or failure) or as soon as the
Gap progress reaches a given progress value. This progress value is
defined when the tracker.waitForRange() method is called; this method
has been modified to accept a range and another listener's range to
operate on.

Fix Incorrect Snapshot Shar Status for DONE Shards in Running Snapshots (#58390) (#58593)
Minor bugs/inconsistencies:

If a shard hasn't changed at all we were reporting `0` for total size and total file count
while it was ongoing.

If a data node restarts/drops out during snapshot creation the fallback logic did not load the correct statistic from the repository but just created a status with `0` counts from the snapshot state in the CS. Added a fallback to reading from the repository in this case.

[7.x] Fix negative limiting with fewer PARTIAL snapshots than minimum required (#58563) (#58569)
In SLM retention, when a minimum number of snapshots is required for retention, we prefer to remove
the oldest snapshots first. To perform this, we limit one of the streams, in a rare case this can
cause:

```
[mynode] error during snapshot retention task
java.lang.IllegalArgumentException: -5
	at java.util.stream.ReferencePipeline.limit(ReferencePipeline.java:469) ~[?:?]
	at org.elasticsearch.xpack.core.slm.SnapshotRetentionConfiguration.lambda$getSnapshotDeletionPredicate$6(SnapshotRetentionConfiguration.java:195) ~[?:?]

When certain criteria are met. This commit fixes the negative limiting with `Math.max(0, ...)` and

Fix two scripted_metric bugs (backport of #58547) (#58565)
Fixes two bugs introduced by #57627:
1. We were not properly letting go of memory from the request breaker
   when the aggregation finished.
2. We no longer supported totally arbitrary stuff produced by the init
   script because we *assumed* that it'd be ok to run the script once
   and clone its results. Sadly, cloning can't clone *anything* that the
   init script can make, like `String` arrays. This runs the init script
   once for every new bucket so we don't need to clone.

Introduce node.roles setting (#58512)
Today we have individual settings for configuring node roles such as
node.data and node.master. Additionally, roles are pluggable and we have
used this to introduce roles such as node.ml and node.voting_only. As
the number of roles is growing, managing these becomes harder for the
user. For example, to create a master-only node, today a user has to
configure:
 - node.data: false
 - node.ingest: false
 - node.remote_cluster_client: false
 - node.ml: false

at a minimum if they are relying on defaults, but also add:
 - node.master: true
 - node.transform: false
 - node.voting_only: false

If they want to be explicit. This is also challenging in cases where a
user wants to have configure a coordinating-only node which requires
disabling all roles, a list which we are adding to, requiring the user
to keep checking whether a node has acquired any of these roles.

This commit addresses this by adding a list setting node.roles for which
a user has explicit control over the list of roles that a node has. If
the setting is configured, the node has exactly the roles in the list,
and not any additional roles. This means to configure a master-only
node, the setting is merely 'node.roles: [master]', and to configure a
coordinating-only node, the setting is merely: 'node.roles: []'.

With this change we deprecate the existing 'node.*' settings such as
'node.data'.

[7.x] [ML] make waiting for renormalization optional for internally flushing job (#58537) (#58553)
* [ML] make waiting for renormalization optional for internally flushing job (#58537)

When flushing, datafeeds only need the guaruntee that the latest bucket has been handled.

But, in addition to this, the typical call to flush waits for renormalization to complete. For large jobs, this can take a fair bit of time (even longer than a bucket length). This causes unnecessary delays in handling data.

This commit adds a new internal only flag that allows datafeeds (and forecasting) to skip waiting on renormalization.

Add Variable Width Histogram Aggregation (backport of #42035) (#58440)
Implements a new histogram aggregation called `variable_width_histogram` which
dynamically determines bucket intervals based on document groupings. These
groups are determined by running a one-pass clustering algorithm on each shard
and then reducing each shard's clusters using an agglomerative
clustering algorithm.

This PR addresses #9572.

The shard-level clustering is done in one pass to minimize memory overhead. The
algorithm was lightly inspired by
[this paper](https://ieeexplore.ieee.org/abstract/document/1198387). It fetches
a small number of documents to sample the data and determine initial clusters.
Subsequent documents are then placed into one of these clusters, or a new one
if they are an outlier. This algorithm is described in more details in the
aggregation's docs.

At reduce time, a
[hierarchical agglomerative clustering](https://en.wikipedia.org/wiki/Hierarchical_clustering)
algorithm inspired by [this paper](https://arxiv.org/abs/1802.00304)
continually merges the closest buckets from all shards (based on their
centroids) until the target number of buckets is reached.

The final values produced by this aggregation are approximate. Each bucket's
min value is used as its key in the histogram. Furthermore, buckets are merged
based on their centroids and not their bounds. So it is possible that adjacent
buckets will overlap after reduction. Because each bucket's key is its min,
this overlap is not shown in the final histogram. However, when such overlap
occurs, we set the key of the bucket with the larger centroid to the midpoint
between its minimum and the smaller bucket’s maximum:
`min[large] = (min[large] + max[small]) / 2`. This heuristic is expected to
increases the accuracy of the clustering.

Nodes are unable to share centroids during the shard-level clustering phase. In
the future, resolving https://github.com/elastic/elasticsearch/issues/50863
would let us solve this issue.

It doesn’t make sense for this aggregation to support the `min_doc_count`
parameter, since clusters are determined dynamically. The `order` parameter is
not supported here to keep this large PR from becoming too complex.

[7.x][ML] Change inference default field name to <dep_var>_prediction… (#58546)
This changes the default value for the results field of inference
applied on models that are trained via a data frame analytics job.
Previously, the results field default was `predicted_value`. This
commit makes it the same as in the training job itself. The new
default field is `<dependent_variable>_prediction`. Apart from
making inference consistent with the training job the model came
from, it is helpful to preserve the dependent variable name
by default as it provides some context to the user that may
avoid confusion as to which model results came from.
